Unity Simulation Test

This repository provides a simple tutorial demonstrating how to connect a ROS2 node to a Unity simulation.
The project contains two main folders:

• RoboticsTestDemo — a prebuilt Unity simulation
• robotics_ws — a ROS2 workspace configured to communicate with the Unity demo

---

1. Running the Unity Simulation

To start the demo environment, open a terminal (Ctrl + Alt + T) navigate to the app folder and run the app:

cd <path_to_workspace>/RoboticsTestDemo
chmod +x RoboticsTestDemo.x86_64
./RoboticsTestDemo.x86_64

A window will open showing a simple scene containing a cube:

2. Setting Up the ROS2 Workspace

Open a second terminal (Ctrl + Alt + T), navigate to the robotics_ws folder, and install the ROS_TCP_Endpoint package:

cd <path_to_workspace>/robotics_ws/src
git clone https://github.com/Unity-Technologies/ROS-TCP-Endpoint.git -b main-ros2 

ROS_TCP_Endpoint enables communication between the Unity simulation and your ROS2 nodes.

Now build and source your workspace:

cd ../
colcon build 
source install/setup.bash

3. Running the Example ROS2 Node

Launch the test node with:

ros2 launch pose_test test.launch.py

If everything is configured correctly, the cube in the Unity window will begin floating and rotating:
